Tumor cells in blood samples could predict prostate cancer spread

Researchers have found a group of circulating tumour cells in prostate cancer patient blood samples which are linked to the spread of the disease, according to new research* presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool.

This is the first time these cell types have been shown to be a promising marker for prostate cancer spread.

In a study of around 80 samples from men with prostate cancer, scientists at the Barts Cancer Institute at Queen Mary University looked for cells that were gaining the ability to migrate and invade through the body.**

Samples with more of these cells were more likely to come from patients whose cancer had spread or was more aggressive.

This means that, in the future, these particular cells could potentially be used as a marker to monitor prostate cancer patients and predict if the disease is going to spread -- alongside other monitoring techniques.

There are around 46,500 new cases of prostate cancer each year in the UK, and around 11,000 people die from the disease each year.

Dr Yong-Jie Lu, lead author from QMUL's Barts Cancer Institute, said: "Our research shows that the number of these specific cells in a patient's sample is a good indicator of prostate cancer spreading. By identifying these cells, which have gained the ability to move through the body, we have found a potential new way to monitor the disease.

"If we're able to replicate these studies in larger groups of people, we may be able to one day predict the risk of someone's cancer spreading so they can make more informed treatment decisions."

Dr Chris Parker, Chair of the NCRI's Prostate Cancer Clinical Studies Group, said: "There's a need to develop better tests to identify and monitor men with aggressive prostate cancer. This research has found a promising new marker that could one day make it to the clinic to guide treatment decisions."

This research was funded by Orchid Cancer Appeal, ANGLE plc and Chinese Scholarship Council. The scientists used a highly innovative cell separation technology Parsortix™, developed by UK company ANGLE plc that is able to capture the circulating tumour cells.

About ANGLE plc

ANGLE is a specialist medtech company commercialising a disruptive platform technology that can capture cells circulating in blood, such as cancer cells, even when they are as rare in number as one cell in one billion blood cells, and harvest the cells for analysis.

ANGLE's cell separation technology is called the ParsortixTM system and it enables a liquid biopsy (simple blood test) to be used to provide the cells of interest. Parsortix is the subject of granted patents in Europe, the United States, Canada, China and Australia and three extensive families of patents are being progressed worldwide. The system is based on a microfluidic device that captures live cells based on a combination of their size and compressibility. Parsortix has a CE Mark for Europe and FDA authorisation is in process for the United States.

ANGLE has established formal collaborations with world-class cancer centres. These Key Opinion Leaders are working to identify applications with medical utility (clear benefit to patients), and to secure clinical data that demonstrates that utility in patient studies. Details are available here http://www.angleplc.com/the-company/collaborators/

The analysis of the cells that can be harvested from patient blood with ANGLE's Parsortix system has the potential to help deliver personalised cancer care offering profound improvements in clinical and health economic outcomes in the treatment and diagnosis of various forms of cancer.

The global increase in cancer to a 1 in 3 lifetime incidence is set to drive a multi-billion dollar clinical market. The Parsortix system is designed to be compatible with existing major medtech analytical platforms and to act as a companion diagnostic for major pharma in helping to identify patients that will benefit from a particular drug and then monitoring the drug's effectiveness.

As well as cancer, the Parsortix technology has the potential for deployment with several other important cell types in the future.

ANGLE stock trades on the AIM market of the London Stock Exchange under the ticker symbol AGL and in New York on the OTC-QX under the ticker symbol ANPCY. For further information please visit: http://www.angleplc.com
